Sports Training System and Method

ABSTRACT

Provided is a modular sports training system that can be assembled, placed on a supporting surface, and stood upon by a person during sports training activities. The system is adapted to be assembled with one or more modules. One module may be disposed at a non-parallel angle to another module. One module may be aligned with another module. The non-parallel angle allows a person standing on the system to place one foot on one module and another foot on another module at the non-parallel angle, such as in a swing or batter&#39;s stance, and allows the person to stand in a stable manner while encouraging certain positioning of the feet during the sports training activities. Modules can be coupled by an interlocking protrusion and receiver arrangement, such as by inserting a protrusion of one module into a receiver of another module when the modules are unaligned relative to each other and then twisting the modules into alignment.

STATEMENT REGARDING FEDERALLY-SPONSORED RESEARCH OR DEVELOPMENT

Not applicable.

BACKGROUND

The invention relates generally to the field of sports. More specifically, it relates to a system and method of training persons for sports activities, such as batting, swinging, and throwing.

Sports training devices are generally designed for strength, agility, and coordination of motor skills. The devices can be complicated or simple, with even simple devices sometimes filling an unmet need.

In baseball or softball, for example, a proper batting stance is important for training, especially in the formative years of a batter. Similar positional training, which includes training for spatial balance and/or stance, are required for other sports activities, such as golf, tennis, etc. Generally, for baseball or softball, the feet are spaced at a shoulder distance and transverse to the direction of an oncoming ball with knees slightly bent and body weight slightly weighted to the back leg. Upon the ball approaching, the batter smoothly steps in with a front foot in a direction parallel to an imaginary line from the ball to the pitcher leaving the back foot in position. One of the common mistakes for batters is to step away or “outside” from the imaginary line, which can cause the batter to swing outside the ball path and miss the ball. The batter may also step inside toward the imaginary line and “crowd” that ball, resulting in a poorly hit ball by hitting the ball with a portion of the bat that is inside the “sweet spot” of the bat. Thus, one aspect of training is to encourage and ingrain proper stepping techniques during the swing.

Other training techniques, taking baseball and softball as examples, include proper pitching techniques from a mound. A pitcher typically steps on a “pitching rubber” with a back foot and throws the ball while the front foot steps forward toward the batter at the home plate. However, the height of a pitching mound for the stationary back foot to the height of the ground where the stepping front foot lands can differ by several inches. An inexperienced pitcher can lose balance, and therefore control and speed, during the process with the several inches of elevation difference from mound to ground. A suitable pitching and/or sports training device can assist in developing the balance and skill needed for any sports training activity.

One training device is a “T” shaped wooden arrangement made from two (2) wooden pieces attached together with “L” brackets and screws. The wooden device can be laid on the ground and the batter can stand on the wooden arrangement. A back foot stands on the short length of the “T” and the front foot stands on the long length of the “T.”

Commercially available training devices for certain sports have included “The Baseballance,” “The Batter's Edge Balance Beam,” “The Fix,” available through statsint1.com, and the Pro Stance training aid.

While the benefits of training devices are known, none of the above examples meet the market needs in a totally satisfactory manner. For example, the above “T” wooden arrangement is heavy, and because it is screwed together, does not easily break into separate pieces. If not taken apart, the device will not fit in a passenger car and requires a large SUV or pick-up truck, should a person desire to transport this wooden arrangement. The above Baseballance device is not stable as a supporting surface with its rocking function. The Batter's Edge Balance Beam and the Pro Stance training aid devices are straight beams. The Fix device appears directed to keeping one foot stationary without affecting both feet.

There remains a need for an improved, lightweight, variable length, portable sports training assembly that can be and are at least easily assembled and disassembled and suitable for use with a variety of different sports that require balance, coordination, and mastery while performing said sport.

The figures described above and the written description of specific structures and functions below are not presented to limit the scope of what Applicant has invented or the scope of the appended claims. Rather, the figures and written description are provided to teach any person skilled in the art how to make and use the invention for which patent protection is sought. Those skilled in the art will appreciate that not all features of a commercial embodiment of the invention are described or shown for the sake of clarity and understanding. Persons of skill in this art will also appreciate that the development of an actual commercial embodiment incorporating aspects of the present invention will require numerous implementation-specific decisions to achieve the developer's ultimate goal for the commercial embodiment. Such implementation-specific decisions may include, and likely are not limited to, compliance with system-related, business-related, government-related, and other constraints, which may vary by specific implementation, location, and from time to time. While a developer's efforts might be complex and time-consuming in an absolute sense, such efforts would be, nevertheless, a routine undertaking for those of ordinary skill in this art having benefit of this disclosure. The use of a singular term, such as, but not limited to, “a,” is not intended as limiting of the number of items. Also, the use of relational terms, such as, but not limited to, “top,” “bottom,” “left,” “right,” “upper,” “lower,” “down,” “up,” “side,” and the like are used in the written description for clarity in specific reference to the figures and are not intended to limit the scope of the invention or the appended claims.

The disclosure provides a modular sports training system adapted to be assembled, placed on a supporting surface, and stood upon by a person during sports training activities. The system is adapted to be assembled with one module being disposed at a non-parallel angle to another module. The non-parallel angle allows a person standing on the system to place one foot on one module and another foot on another module at the non-parallel angle, such as in a batter's stance, and allows the person to stand in a stable manner while encouraging certain positioning of the feet during the sports training activities. The modules can be coupled by an interlocking protrusion and receiver arrangement. The modules can be coupled together by inserting a protrusion of one module into a receiver of another module when the modules are unaligned relative to each other; and then twisting the modules into alignment.

FIG. 1 is a perspective schematic view of an exemplary embodiment of a modular sports training assembly having a plurality of assembled modules. FIG. 2 is a perspective schematic view of the exemplary modular sports training assembly of FIG. 1 with the plurality of assembled modules viewed from an opposite side. FIG. 3 is a top schematic view of an exemplary module of the modular sports training assembly. FIG. 4 is a side schematic view of the exemplary module. These and other figures will be described in conjunction with each other.

The sports training assembly 2 includes at least one or two modules and generally three or more modules. In at least one embodiment, each module can be interchangeable with the other modules, so that each module can be coupled to another module in like manner. In the exemplary embodiment shown in FIG. 1, a first module 4 can be coupled to a second module 6. The second module 6 can in turn be coupled to a third module 8. The order of the modules can vary, because the modules are interchangeable. In one exemplary embodiment, the first module 4 is coupled crossways or lateral to the second module 6, and is therefore non-parallel to the second module 6. Any suitable non-parallel angle can be used, and in the first exemplary embodiment, the modules are at right angles. The third module 8 can be coupled parallel to the second module, 6, so that it is aligned with the second module 6. As will be detailed further herein, the modules have various receivers and protrusions to allow the coupling and interchangeability described herein. The modules generally have a top 10, a first side 12, and a second side 14. The sides are at non-parallel angles to the top 10. Further, the modules have a first end 16, and a second end 18 at non-parallel angles to the sides 12, 14, and the top 10. Further, the modules generally have a bottom 20 for use in supporting the modules on a surface, such as the ground. For example without limitation, the sides can be approximately four (4) inches tall, the top can be approximately six (6) inches wide, and the length along the side can be approximately 36 inches long, including the length of the protrusion. It has been found that a dimension of six (6) inches for the width is approximately wide enough for a person to stand crossways in a transverse manner to the top and still have sufficient support. The length of 36 inches has been found to be advantageous for storing bats and various items in the tube 78 described in FIG. 10. Naturally, other dimensions and proportions can be used and such examples are only offered as non-limiting illustrations.

The modules further include a protrusion 22 disposed on the first end 16, and a receiver 24 disposed on the second end 18, opposite from the first end 16. Further, the modules have a receiver 26 on at least one of the sides 12, 14, and generally on both sides in the exemplary embodiment. As an alternative embodiment, the receivers on the side of the modules can be located at positions other than shown, including toward one end or another, and further can include multiple receivers on the sides or other surfaces. The protrusion 22 can include a first protrusion wing 40 and a second protrusion wing 42. The receivers 24, 26 can include a receiver tab 33. The protrusion 22 of one module is sized and shaped to fit within one or more of the receivers 24, 26 of another module. The protrusion 22 is adapted to be rotated to a desired angular position within the receiver 24, 26, so that the wings 40, 42 are restrained within the module walls adjacent the receiver to couple the modules together, and the wings are restricted from further rotation by the receiver tab 33.

FIG. 5 is a detail perspective schematic view of an exemplary receiver of the module. The receivers 24, 26 are generally formed through a wall of the modules, such as module 4. The receivers 24, 26 can have a variety of shapes. In at least one embodiment, the receivers 24, 26 can include a main receiver portion 28 and a first receiver extension 30. In some embodiments, the receivers 24, 26 can also include a second receiver extension 32. In general, the receivers 24, 26 will have a shape that allows the protrusion 22, described herein, to be inserted and restrained therein. Thus, generally the main receiver portion 28 will have a contour periphery that is closer to a center of the receiver than the distance that a contour periphery of the receiver extension is to the receiver center. The exemplary receivers 24, 26 illustrate two receiver extensions, but the number of receiver extensions can vary from one to many.

Further, the receivers 24, 26 in a module can be tilted or rotated relative to a datum plane for assembly or disassembly with a corresponding protrusion of an adjacent module. For example, a datum plane 34 can be defined as a horizontal plane passing through a center of the receiver when the module top 10, shown in FIGS. 1 and 2, is horizontal. A positional angle “α” of a receiver extension 30 relative to the plane 34 can be defined from the plane to a line 36 drawn through a center of the receiver extension and the center of the receiver. The receivers 24, 26, and the module associated with that particular receiver, can be rotated from a first orientation relative to the datum plane 34 to a second orientation, thus changing the angle “α”. The rotated receiver can be aligned and coupled to an adjoining protrusion at the rotated orientation and then rotated to a different orientation, including returning to the first orientation, to couple the receiver and protrusion together, such as in a locking engagement. A receiver tab, described herein, can be formed inside of the receivers 24, 26 to limit the rotation of the protrusion 22 in the receiver. Alternatively, the receiver tab can be formed outside of the receiver area on the module external surfaces or other suitable locations to restrict the rotation of the protrusion. The above example illustrates the rotation of the receiver and is equally applicable to the rotation of the protrusion to be coupled to the receiver, or the rotation of both the receiver and protrusion to assist in coupling the receiver and the protrusion together.

FIG. 6 is a detail perspective schematic view of an exemplary protrusion of the module. FIG. 7 is a detail top schematic view of the protrusion of FIG. 6. FIG. 8 is a detail side schematic view of the protrusion of FIG. 6. FIG. 9 is a detail partial cross sectional schematic view of the protrusion of FIG. 6. The figures will be described in conjunction with each other. The particular arrangement and profile of the exemplary protrusion 22 is designed to fit within the receiver 24, described in FIG. 5. However, it is understood that different variations including non-symmetrical, offset, and other variations are possible for the shape of the protrusion 22.

The exemplary protrusion 22 includes a main protrusion portion 38 that is coupled to the first end 16 of an exemplary module. The main protrusion portion 38 extends in a direction outwardly from the first end 16 for a thickness 44, and has an outer surface 50 disposed distally from the first end. A first wing 40 and a second wing 42 extend radially from the main protrusion portion 38. A peripheral surface 56 of the wings is generally shaped to allow insertion of the protrusion 22 into the receivers 24, 26, and particularly into the receiver extensions 30, 32. The wings 40, 42 are spaced longitudinally outward from the end 16 by a gap 48. The wings can have a first wing thickness 46 at an edge of the wing that enlarges to a thicker second wing thickness 47 with an outer surface 52 disposed distally from the module end 16. The varying thickness allows the wings 40, 42 to tighten the coupling engagement between adjacent modules as the wings are rotated relative to the receivers 24, 26, so that the outer surface 52 of the wings engages a module inner wall surface adjacent the receivers 24, 26.

In at least one embodiment, a first protrusion tab 88 and a second protrusion tab 90 with an outer surface 92 extend longitudinally outward from the main protrusion portion 38. Thus, the protrusion tabs 88, 90 relative to the main protrusion portion 38 form a recess having a depth 54 between the outer surface 50 of the main protrusion portion 38 and the outer surface 92 of the protrusion tabs 88, 90. This recess is used to help couple the modules together during transportation, as shown in FIG. 11.

FIG. 10 is a perspective schematic view of an exemplary disassembled module. In at least one embodiment, the modules, such as module 4, can be formed in multiple portions and coupled thereto. For example, the module 4 can be formed from a first portion 4A and a second portion 4B that can be adhesively connected together or otherwise fastened together. The module portion 4A can be formed with an outer wall 70 that can be coupled to a corresponding outer wall on the other module portion 4B. In some embodiments, the outer wall 70 may include various locators, ridges, valleys, and other items that may assist in proper alignment and coupling of the two module portions. Additionally, screws and other fasteners can be used to retain the module portions together, such as by tightening a screw or other fastener through a thin tube with a shoulder (in place of a pin locator) on one module portion into a corresponding hole on the other module portion, as customarily is done by those in the art. The fasteners may be particularly useful while any applied adhesive cures between the module portions. The protrusions and receivers described above can be formed as portions in each module portion. Each portion of a receiver can include one or more protrusion tabs 33. Further, the module portions 4A, 4B can include braces 72 disposed at various locations along a length of the module portions. In at least one embodiment, the brace 72 can be formed with a cavity 74, so that a series of braces forms a series of cavities along a longitudinal axis 76 of the module portions. The opening 74 can be sized to allow a tube 78 to be disposed therein. Thus, when the module portions 4A, 4B are coupled, the tube 78 is encased and secured between the module portions and thus within the module 4. The term “tube” is used broadly herein to include any shaped hollow member, including those members having a cross section that is round, elliptical, square, rectangular, and other geometric or arbitrary shapes, and further can vary in shape and size along the longitudinal axis 76. In at least one embodiment, the tube 78 allows a bat to be disposed and stored therein during transportation of the sports training assembly to a sports location. Further, the tube can be used to store beverages and other refreshments, balls, and other items that fit therein. It has generally been found that a tubular inside cross-sectional dimension of three (3) inches is suitable for storing baseballs, bats, cans, and bottled beverages.

FIG. 11 is a perspective schematic view of the plurality of modules of the exemplary modular sports training assembly ready for transportation to a sports training location. The sports training assembly 2 can advantageously be disassembled and assembled for ease of transportation to sports training locations. In one embodiment, the modularity of the assembly allows ease of stacking and storage. For example, the three illustrated modules 4, 6, 8 can be stacked and held in place by a carrying strap 60. The strap 60 can align on the first end 16 and pass over the recessed outer surface 50 between the first and second protrusion tabs 88, 90 on each of the modules. A strap saddle 66 around one or more ends 18 can be used to hold the strap 60 in position. A latch 64 can be used to tighten the strap around the modules and secure the modules in position. A carrying handle 68 can be included with the strap. Other carrying cases can be provided, such as a duffle bag style case that substantially surrounds the modules, and the examples are not limiting.

Having described the elements of the sports training assembly, an exemplary method of assembling the sports training assembly is described below. The first module 4 can be positioned on a surface such as the ground, and the second module 6 positioned at a non-parallel angle to the first module 4. A protrusion 22 on the second module 6 can be aligned with a receiver 26 on the first module 4. The module 6 with the protrusion 22 can be rotated to an angle to match the angle a of the receiver 26 relative to the datum plane 34, illustrated in FIG. 5. The protrusion 22 on the second module 6 will generally be rotated at an angle relative to the module 4, although it is understood that the first module 4 can be rotated to match the alignment of the protrusion on the module 6, or both modules can be rotated to align the receiver and the protrusion. Thus, at the time of insertion of the protrusion 22 with the receiver 26, the top surfaces 10 of the modules 4 and 6 are not aligned, because one module is rotated at an angle relative to the other module. The protrusion 22 on the module 6 can be inserted into the receiver 26 until the end 16 of the second module 6 abuts the side 14 of the first module 4. The second module 6 can be rotated with a twist, such as in the opposite direction that it was rotated earlier for the insertion, to couple the wings 40, 42 behind the interior surfaces of the wall of module adjacent the receiver 26. The rotation of the second module 6 relative to the module 4 can terminate when the top surface 10 of the second module 6 is aligned with the top surface 10 of the first module 4. In embodiments having protrusion tabs 33 in the receivers, the module is positively restricted from further rotation when the wings 40, 42 engage the protrusion tabs.

The length of the sports training assembly 2 can be increased by coupling the third module 8 to the second module 6. In a similar fashion as described above, the module 8 can be rotated at an angle a to align its protrusion 22 with the corresponding receiver 24 on the end 18 of the second module 6. The protrusion 22 can be inserted in the receiver 24, and the module 8 rotated relative to the second module 6 to couple the protrusion 22 in the receiver 24 and align the top surface 10 of the third module 8 with the top surface 10 of the second module 6.

In the exemplary embodiment, with the above exemplary dimensions, the assembly forms a length of about 36 inches along the first module 4 and a cumulative length of about 78 inches that includes the width of the first module and length of the second and third modules. It is believed that such lengths are suitable for most stances of batters and other sports persons that vary their strides from one position to another during a sports training activity.

If not already positioned, the various modules can be placed on the ground or other suitable supporting surface. A person, such as a batter, can stand on the top 10 of the modules to conduct a sports training activity. When assembled, the sports training assembly lies flat on the ground and in at least one exemplary use, a batter will stand in the position of a hitter in the “batter's box” with the batter's back foot (that is, the foot farthest from the pitcher's mound and oncoming ball) standing on the top 10 of the module 4. The batter's front foot (that is, the foot closest to and in the general direction of the pitcher) will stand on the top surface 10 of the second module 6, the third module 8, or both. Generally, the back foot can be aligned in the longitudinal direction of the first module 4 and the front foot can be positioned transverse to the longitudinal direction of the second module 6 and the third module 8.

As the ball approaches the batter, and the batter takes a step and increases his stride, the back foot will generally stay positioned on the top surface 10 of the first module 4, while the front foot will step along the length of the top surfaces 10 of the modules 6, 8 to a full stride position. The batter will know in real time whether the front foot has stepped inappropriately outside or inside relative to the trajectory of the ball if the foot leaves the width of the top 10 of the modules 6, 8.

Upon completion of the sports training activities, the modules can be disassembled, stacked together, and transported to a vehicle or other storage place for the next time a sports training activity occurs.

Various accessories can be used with the sports training assembly 2. For example, in training baseball players to pitch from a pitchers' mound, the sports training assembly 2 can approximate the general distance by which a center of a pitcher's mound is higher than the peripheral edge of the pitcher's mound. When a pitcher pitches, the pitcher's back foot will be at the highest point of the pitcher's mound. As the pitcher steps forward during the pitch toward the home plate and batter, the front foot steps down the slope of the pitcher's mound, resulting in an elevation of the front foot that is several inches lower than the back foot. In practice, it is rare to offer a pitcher's mound to several pitchers concurrently, because access to multiple pitcher's mounds at most practice fields at the same time is difficult. The present invention can also provide a pitching accessory illustrated in FIG. 12 and described below.

FIG. 12 is a perspective schematic view of an exemplary embodiment of a modular sports training assembly with a pitching accessory. The pitching accessory 82 generally includes a sloped surface 84 that on one end is coupled to one or more of the modules 4, 6, 8, described above, of the sports training assembly 2 and on the other end is generally supported by the ground 80. The length of the sloped surface 84 can be about 36 inches, although other lengths can be used. The sloped surface 84 can simulate the approximate drop of a typical pitcher's mound and provide more realistic training for a pitcher when the pitcher pitches from a pitcher's mound. The pitching accessory 82 can further include a protrusion 22 as described above that can be used to couple the pitching accessory to the one or more modules 4, 6, 8 in the receiver 26, as described above for coupling the modules together. The ease of movement of the sports training assembly 2 and the pitching accessory 82 can allow coaches and players to have simulated pitching mounds at a wider variety of locations and improve the ability of multiple pitchers to train by pitching concurrently from multiple sports training assemblies and pitching accessories. In general, a vacant strip of land that is approximately 60 feet long by 5 feet wide can provide sufficient room for each pitcher to train using the sports training device 2 with the pitching accessory 82.

The sports training assembly 2 may include at least one module, or two modules, or more modules, including as many as six or more modules. In one or more embodiments, each module can be interchangeable with the other modules, so that each module can be coupled to another module in a like manner. In the exemplary embodiments shown in FIGS. 14, 15 and 16, a first module 4 is shown. In one or more embodiments, first module 4 may provide a sports training assembly 2. A first module 4 can in turn be coupled to a second module 6 to provide a sports training assembly 2. A second module 6 can in turn be coupled to a third module 8 as depicted in FIG. 16 to provide a sports training assembly 2. Again, ordering and/or coupling of the modules can vary, because the modules are interchangeable.

As depicted in FIG. 16, the first module 4 may be coupled to an end of the second module 6, and aligned and/or in series with the second module 6. A third module 8 can be further coupled in series with the second module, 6, so that it is aligned and/or in series with the second module 6. A fourth module 7 may be further coupled with the first module 4, and/or, the second module 6, and/or the third module 8, the latter of which is shown in FIG. 16. In FIG. 16, the fourth module 7 is also coupled at its side with a side of the first module 4, and in this configuration can be considered to be in parallel and/or in series with the first module 4. Any suitable arrangement of modules may be utilized with the modules described herein, in which the plurality of modules can extend the length and/or width of the sports training assembly 2 beyond the length and/or width of the first module 4 in any desired direction and/or arrangement.

As detailed above, the modules have various receivers and protrusions to allow the coupling and interchangeability described herein. The modules of FIGS. 14, 15 and 16 generally have at least at least two receivers and at least one protrusion. Referring to FIG. 14, as an example, the module 4 of the sports training assembly 2 has a top 10, a first side 12, and a second side 14 that form the outer wall 70. The sides are at non-parallel angles to the top 10. Further, the modules have a first end 16, and a second end 18 at non-parallel angles to the sides 12, 14, and the top 10. Sides and ends may be perpendicular, forming a right angle at their intersection. Each module further includes the protrusion 22 and at least one and often at least two receivers (24 and/or 26). One receiver 24 may be disposed on the second end 18. Another second receiver 26 may be disposed on one side (12 or 14) or on both side 12 and side 14. As described above, alternative arrangements of receivers and protrusions other than shown may be provided with any module described herein, including additional protrusions as well as multiple receivers on any one or more side, end, or other surface. And, the receivers 24, 26 may have any shape, including the shape shown with the module 4 of FIGS. 14, 15 and 16.

As with protrusions described previously, the protrusion 22 can include the first protrusion wing 40 and the second protrusion wing 42. The receivers 24, 26 can include the receiver tab 33 and/or the first receiver extension 30. The second receiver extension 32 may or may not be included with the receiver of module 4 as depicted with any of FIG. 14, 15 or 16. As described previously, each protrusion 22 of the first module 4 is sized and shaped to fit within one or more receivers (24, 26) of any complementary module that the first module 4 will be secured to and/or mated with. In one or more embodiments and as described previously, the protrusion 22 of the first module 4 may be adapted to be inserted (often at an angle) and further rotated to a desired angle and to be secured with and/or positioned within any receiver (24, 26) of any other module. When wings 40, 42 are present, they assist in restraining the first module 4 with the receiver (24, 26) of another module to which the first module 4 is coupled with. When receiver tab 33 is present, the receiver tab 33 may assist in restricting further motion of the protrusion 22 with respect to the receiver (24, 26) of the other module to which the protrusion 22 is mated with. Each or some of the receivers (24, 26) may be further configured with collars 39 as depicted in FIGS. 14 and 15, in which said collars may be adjacent to or spaced some distance apart from the wall 70 in which the receivers (24, 26) are formed. Collars 39 when included may provide additional reinforcement, such as for protrusions 22. Collars 39 may have an dimensional shape or configuration that resembles the general configuration of the receiver (24, 26). Collars 39 may also have an dimensional shape or configuration that differs from the configuration of receivers (24, 26); however said shape will allow the corresponding receiver (abutting or spaced apart) to accept the protrusion and the shape of collars 39 will generally be sufficiently configured to allow the protrusion 22 to form a secure relationship with the receiver to which it is coupled with. In some embodiments, an outer surface of collars 39, or at least part of their outer surface that permits entry of the protrusion 22, may fit with or contact or otherwise abut and help accommodate at least a portion of the protrusion 22 near its end when the protrusion 22 is received by the receiver (24, 26).

The module 4 further includes the bottom 20 for utilization and for supporting the one or more modules on a surface (e.g., support surface, such as the ground, grass, turf, etc.), and interior space 35. Bottom 20 or at least a portion of the surface that forms the bottom 20 (as depicted in FIGS. 14 and 15, may further comprise one or more slots or grooves 41 and/or one or more prominences 43. Slots 41 and prominences 43 may mate with corresponding prominences 43 and slots 41, respectively, with modules when said modules are so-coupled as described previously. In some embodiments, the respective slots 41 and/or prominencse 43 of coupled modules may assist in the actual coupling and/or aligning of the so-coupled modules, such as when the first module (e.g., module 4 or 4A) is coupled with the second module (e.g., module 6 or 4B, respectively) in the manner depicted in FIG. 10. In some embodiments, the slots 41 and/or prominences 43 may also assist when coupling and/or aligning the first module (e.g., module 4 or 4A) with a plate 25, such as depicted in FIG. 13, in which the plate 25 includes respective prominences 43 and/or slots 41 on its inner surface (not shown) for coupling with and/or aligning with those formed on the bottom 20 of the first module (e.g., the module 4 or 4A). Slots 41 and/or prominences 43 may also assist in preventing lateral displacement of the module (e.g., module 4 or 4A) when provided on the support surface. In design, the bottom 20 may be more extensive or may be less extensive than is shown in FIGS. 14 and 15, while providing sufficient allowance to accommodate the protrusion 22 and the one or more receivers (24, 26).

In some embodiments, the interior space 35 includes braces 72 disposed at various locations along a length of the module. In some embodiments, braces 72 are spaced apart in an ordered manner. In some embodiments, braces 72 are evenly spaced apart. Braces 72 may extend from the first side 12 (or from the wall 70 of first side 12 formed therefrom) to the second side 14 (or to the wall 70 of second side 14 formed therefrom). Alternative arrangements are also contemplated. Some braces 72 may help support and contact opposing ends of collars 39, while some braces 72 may be formed in parallel with or without contact with collars 39. Braces 72 may comprise an extended portion 71 that cooperates with the bottom 20 for reinforcement of and/or for holding the module on the support surface. The interior space 35 may further comprise stops 31. Stops 31 may assist in bearing and/or distributing load. Stops 31 may assist in preventing lateral displacement of the module when provided on the support surface. Stops may be formed integrally (molded with) the module or be later fitted to the module (e.g., via insertion and/or by adhesion, etc., in a mated hole). The extended portion 71 of braces 72 may be further configured with members 31. Members 31 may be integral with the extended portion 71 (e.g., molded with) or may be fitted in holes 33, which would be configured on the extended portion 71 to accept the members 31. Members 31 whether fitted after or fitter integrally with braces 71 are generally configured to extend outwardly beyond the plane formed by the bottom 20. Members 31 may be provided as a means for fastening the plate 25 to the module, in which the means for fastening includes suitable means, such as but not limited to pins, screws, wedges, clips, etc. Members 31 when extending outwardly beyond the plane formed by the bottom 20 may also assist in or serve as a means for preventing lateral displacement of the module when provided on the support surface.

The plate 25 as depicted in FIG. 13 may be positioned on or in conjunction with bottom 20 of any module, such as module 4 of FIG. 14, 15 or 16. In addition or as an alternative to having corresponding slots 41 and/or prominences 43 (ones corresponding with respective prominences 43 and/or slots 41 of the module), the plate 25 may be configured with bores 27 that allow the means for fastening described above to secure the plate 25 with the bottom 20 of the module. Members 31 as depicted in FIGS. 14 and 15 may be used to secure the plate 25 to the bottom 20. The members 31 or alternative types of fasteners (e.g., clips, screws, wedges, ties, etc.) may be independent from the module. In one or more embodiments, the members 31 (or a suitable alternative) are configured to fit securely in holes 33 while passing through bore 27 of plate 25. Members 31 may have a length that prevents an end of each member 31 (the end that enters bore 27) from extending beyond the exterior surface of plate 25 (the exterior surface being the surface used as a surface of the plate 25 that opposes the support surface or ground on which the plate 25 is positioned) when the plate is positioned and secured with the bottom 20 of the module. In this manner, member 31 will not interfere with and/or will not contact the support surface on which the plate 25 is positioned on, when the plate is positioned adjacent to or in contact with the bottom 20 of the module. Alternatively, some or all of the members 31 will have a length that extends beyond the exterior surface of the plate 25 when the plate 25 is fitted or so positioned adjacent to or in contact with the bottom 20. In this embodiment, member 31 may interfere with and/or grip the support surface on which the plate 25 is positioned on. In some embodiments, the plate 25 has the same general outer dimensions as formed by bottom 25. In some embodiments, the plate 25 may be further configured to fit in a recess of the bottom 20. The plate 25 may further comprise one or more recess regions 29, which are regions in which the plate is absent (structurally and materially) in order to accommodate the modular fitting and to allow securement between the protrusion on the first module and the receiver on any second or other module. Said modular fittings between any first module and any second or other module are described in more detail above. Alternatively, or in addition, plate 25 may press fit with at least a portion of bottom 20 or be fitted adjacent to at least a portion of bottom 25. The press fit may include fitting plate 25 in a recess or ridge and valley, or other features formed by or in conjunction with an outer wall formed by bottom 20 that assists in proper alignment and/or coupling of the plate 25 with bottom 20. These configurations of plate 25 may be made so that plate 25 is removable from the bottom 20 of the module. These configurations of plate 25 may also be made so that plate 25 is secured permanently with the bottom 20 of the module.

One or a plurality of modules may be provided with a cover 45, as depicted with a plurality of modules shown in FIG. 16. The cover 45 may be removable or may be permanent. The cover 45 may provide protection for the top 10 of the one or the plurality of modules. The cover 45 may replicate or be utilized to imitate a sports surface. For example, the cover 45 may be turf, or the cover 45 may be artificial grass, or it may be a mat, or it may be a rubber flooring, or it may be a padding. The cover 45 may be secured to the top 10 by any means suitable for securing, such as by mechanically joining, press-fitting, clipping, hinging, tying, looping, screwing, fastening, taping, gluing, cementing, etc. In one example, a combination of loops and hooks (e.g., Velcro®, registered with Velcro Industries B.V., the Netherlands, or some variation thereof) are used to secure the cover 45 to the exposed surface of the top 10 of the one or more modules. The cover may be sized to accommodate the plurality of modules or to accommodate a subset of the plurality of modules or may be sized to accommodate each module individually.

FIG. 16 provides an exemplary embodiment of the modular sports training assembly 2. The modules 4, 6, 8 are coupled end to end in the manner described above, in which a portion of the protrusion 22 at end 16 of module 4 is fitted within the receiver 24 at end 18 of module 6 and a portion of the protrusion 22 at end 22 of module 6 is fitted within the receiver 24 at end 18 of module 8. Additionally, three modules 7 are similarly fitted and aligned with modules 4, 6, 8, so that sides of the three modules 7 align with respective sides of modules 4, 6, 8.
